PIANO-ACTION.

SPECIFICATION forming part of Letters Patent No. 268,563, dated December 5, 1882. Application filed June 1, 1882. (No model) To all whom it may concern:

Be it known that I, HUGO Somme, of the city, county, and State of New York, have invented certain new and useful Improvements in Upright-Piano Actions,of which the following is a specification.

This invention relates to an improved upright-piano action, by which a quick and absolutely certain repetition is obtained; and the invention consists of a hammer-butt having an elbow-shaped arm, with aspring-pressed flange pivoted to the lower end of the arm and suspended therefrom by a .hook, said flange extending forward toward the butt and the actu- 5 ating-jack.

In the accompanying drawings, Figures 1 and 2 represent side views of my improved upright-piano action, showing it respectively in a position of rest and in action.

Similar letters of reference indicate corresponding parts.-

In the drawings, A AA represent the supporting-frame of my improved upright-piano action; B, the hammer; U, the butt, and D the fulcrumed and spring'acted jack, which is operated by the key and suitable transmitting mechanism in the usual manner. The jack D acts upon the lower part of the buttand causes thereby the hammer to strike the string. To the rear part of the butt is applied a fixed elbow-shaped arm, 0, to which is hinged a springpressed flange, E, said flange being hung by a hook, e, to the arm 0, as shown clearlyin Figs. 1 and 2. The flange E extends from the end of the arm 0 forward toward the rear part of the butt 0, and forms a stop or cushion for the jack D as soon as the same is raised, so as to lift the hammer butt, as shown in Fig. 2. The effect of the flange E on thejack D is to limit the motion of the latter and to produce the short stopping of the same. The flange E is connected by a bridle, f, in the usual manner, with an arm,g, of the oscillating lever to which the jack is fulcrumed. The bridle f returns the hammer against its check in the usual manner. As the motion of the jack D is confined and limited by the interposition of the flange E the jack is prevented from leaving the butt farther than necessary for the relief of the hammer from the string, while the cushioning-spring of the flange E enables the jack to adjust itself automatically to any degree of force which is exerted on the key. Thelimited motion of the jack D, combined with the receding of the flange E in response to the greater or less force exerted upon the key and jack, admits of the quick and absolutely certain repetition of the action, without requiring the full return of the key to its normal position.

Having thus described myinvention, lclaim as new and desire to secure by Letters Patent In a repeating action for upright pianos,the combination of a jack, D, hammer-butt 0, having an elbow-shaped arm, 0, and a springpressed flange, E, pivoted to the lower end of the arm (1 and suspended therefrom by hook 6, said flange extending forward into close proximity with the butt 0 and jack D, substantially as set forth.

In testimony that 1 claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
